Mixing Condition and Solid-Liquid and Gas-Liquid Mass Transfer in a Shaking Vessel with Figure-Eight Motion

Abstract

The flow pattern and the solid-liquid and gas-liquid mass transfer coefficients in figure-eight shaking vessels were observed by experimental methods. The flow patterns in the figure-eight shaking vessels changed irregularly with increase in the shaking frequency. The region of the optimum operating condition of the figure-eight shaking was larger than that of the reciprocal shaking. The solid-liquid mass transfer coefficient was correlated with the same correlation as that of the rotary shaking vessel. The gas-liquid mass transfer coefficient of the figure-eight shaking vessel was also correlated with the same type of correlation as that of the rotary shaking vessel.
